The document discusses the treatment of severe asthma exacerbations in the emergency department. It outlines several mainstay treatments including beta-2 agonists, ipratropium, and steroids. For patients not responding to initial treatments, it recommends considering magnesium, intravenous epinephrine, non-invasive positive pressure ventilation, or intubation. The document provides guidance on appropriate ventilator settings and treatments for potential complications of intubation like barotrauma. It concludes by listing additional resources on managing the crashing asthmatic patient.
Atelectasis is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid.

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2. What We Will Talk About
Treatment of Severe Asthma in ED
What works and What Does Not
Treatment of the Crashing Asthmatic
What We Won‟t Talk About
• Treatment of the Mild-Moderate Asthmatic
6. Risk Factors for Death in Asthma
Previous severe exacerbation (ICU/intubation)
2 or more hospitalizations for asthma in 1 year
3 or more ED for asthma in 1 year
Hospitalization/ED visit for asthma in last month
Using >2 MDI short acting β2 agonists in last month
Current or recent use steroids
8. β2-agonists
Camargo CA et al. Continuous versus intermittent beta-agonists
for acute asthma. Cochrane Database Syst Rev. 2003;(4):C
N = 461 Adults and pediatric
Participants got either:
10-30mg albuterol over 2-4 hours OR q20 minute nebulizers,
q30 minute nebulizers, or q1 hour nebulizers.
90% saw no benefit
10% decreased hospital admission rate
CONTINUOUS IS BETTER
9. Ipratropium
The nnt looked at 6 meta-analyses from 1999-2006
Ipratroprium added to beta 2 agonist therapy
N = 1500
Decrease in hospital admission by 9%
NNT = 11.5 (11.5 treated to prevent 1 admission)
3 nebules is the max for 6 hours
IPRATROPIUM GOOD
10. Steroids
Rowe BH et al. Early emergency department treatment of acute
asthma with systemic corticosteroids. Cochrane Database Syst
Rev. 2001;(1):CD002178
12 studies- Steroids given within 1 hour. Both pediatric (PO)
and adult (IV/IM). Followed up between 3 and 21 days.
N = 863
NNT = 5
12.5% were helped by preventing hospital admission
10.0% were helped by preventing asthma relapse
9.1% were helped by preventing a later hospital admission
GIVE STEROIDS
11. Mainstays in Treatment
β2-agonists
Hit „em hard, hit „em long
Anticholinergics
Especially effective in children
3 nebules max for 6 hours
Steroids
Give early but will take time to work
12. Trivia
This resident competed in an Ironman and has the tattoo
to prove it. Additionally, she has this license plate:
15. Magnesium
BH et al. Magnesium sulfate for treating exacerbations of acute
asthma in the emergency department. Cochrane Database Syst Rev.
2000;(2):CD001490.
N = 665 Both pediatric and adult
Most studies gave as bolus (1.2-2gm/20 min, or peds 25-
100mg/kg). 6/7 gave within 1st hour
67% no benefit
33.3% severe asthmatics prevented hospital admission
For severe NNT =2
100% non-severe asthmatics were neither harmed/helped
GIVE MAGNESIUM EARLY
16. IV Epinephrine
Potent, Reduces Airway Resistance
α effect leads to vasoconstriction
1:10000 (crash cart epi)
0.25cc is a 25mcg push if crashing
2.5cc in 250mL NS (1mcg/mL sol‟n) run over 25 min
(10mcg/min)
17. Non-invasive Positive Pressure
Ventilation
Non-invasive positive pressure ventilation for treatment of respiratory
failure due to severe acute exacerbations of asthmaLim WJ, Mohammed
Akram R, Carson KV, Mysore S, Labiszewski NA, Wedzicha JA, Rowe BH,
Smith BJ. December 12, 2012
6 trials, N =206
Compared to usual medical care alone, NPPV reduced hospitalizations,
increased the number of patients discharged from the emergency
department, and improved respiratory rate and lung function
measurements. The application of NPPV in patients with asthma, despite
some promising preliminary results, still remains controversial. Further
studies are needed to determine the role of NPPV in the management of
severe acute asthma and especially in status asthmaticus.
Increases FRC, Decreases WOB
USE NPPV
18. Trivia
This resident is a former cheerleader, went to the best
medical school in the country, hates public speaking, and
is a bad ass rock climber.
21. Intubation
18% mortality if intubated. Probably lower now that we
have better vent settings
Death-asphyxia, tension ptx, reduced venous return
Diaphoretic/Decreased responsiveness
22. Intubate
Lidocaine (1.5mg/kg)
IV or inhaled
Reduces airway responsiveness
Ketamine (1-1.5mg/kg)
Weak bronchodilator
Can consider (0.5mg/kg) in agitated patient
Succ (1.5mg/kg) or Roc (1mg/kg)
Recommend giving ketamine/lido while sitting up and then
laying down and pushing paralytics. Also recommend most
experienced person place ET tube
Have the cric ready
23. Ventilator Settings
Barotrauma, Breathstaking, DEATH
Initial RR 6-8 breaths/min (DO NOT HYPERVENTILATE)
Small TV 5-7cc/kg
Small PEEP (0 or 2)
Large I:E ratio (1:5 up to 1:8)
Don‟t worry about CO2/acidosis
Keep plateau pressure under 30
24. Trivia
This resident is president of AAEM/RSA, is the youngest 2nd
year, is a country line dancing fiend, loves to shoot guns,
has an amazing ability to NEVER be hungover.
27. Barotrauma, Breathstacking,
Decreased Venous Return, DEATH
Fluid bolus 1-2L
d/c ET tube
If O2 sat is >88% manually press on chest for about 60
sec
Bilateral needle decompressions and chest tubes. DO
NOT WAIT FOR X-RAY
28. Summary
Β2 agonists, ipratropium, steroids
Magnesium, IV epinephrine, NIPPV
Intubate using lidocaine, ketamine, paralytic
Low PEEP, low TV, long I:E ration, low RR, watch plateau
pressure
If pt arrests think barotrauma: d/c ET tube, b/l
